To begin with, we can encode data > this way: > first 4 bytes is the # elements > then each 4 byte is the start offset of the element, unless it is negative, > in which case the element is null. > followed by the elements themselves > For example, [10, 11, 12, 13, null, 14], internally should be represented as > (each 4 bytes) > 5, 28, 32, 36, 40, -44, 48, 10, 11, 12, 13, 0, 14 -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
